Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Change Verification Facility

Change
Verification Facility (CVF) is a software system
which integrates the dimensions of Environment, Task, Order and Time
to enable optimal automation. The four
dimensions are harnessed
using a graphic windows application to simplify user selection.

The primary
purpose of CVF is to provide a high degree of test
automation. Scheduled test cases are run
against scheduled
environments with a combination of two options:
(1) start immediately after scheduling
CVF at a time set by the
operator;
(2) run to completion, or quiesce after
a specified amount of time,
or continuously repeat up to a specified number of hours, thus
allowing unattended execution of a set of tests overnight or while
system usage is low.

A "Schedule" window (Figure 1)
defines a two-dimensional array,
with environments on one axis, and tests to be performed against
those environments on the other axis.

The
"Environment" window lists the entries on the environments
axis, and the "tests" window lists the entries on the
"tests" axis.
Figure 2 illustrates the two-dimensional array for the example in
Figure 1.

Note that not
every test is listed against every environment.
This information is stored within the test case and is listed
elsewhere; if a test does not run under an environment, it does not
have an entry for that environment, and hence that particular
environment/test box in Figure 2 will be left blank. The order of
execution of the tests is:
Bring up the environment
Run all the tests which are
applicable
Bring up the next environment
Run all the tests which are
applicable
Bring up the next environment
and so on .......
A third dimension is that of time and repeatability. One "Schedule"
matrix can be executed repeatedly until a set time has elapsed. In
addition to the above three-dimensional representation, it is
possible to submit multiple "Schedule" windows, thus adding a fourth
"order" dimension. It is thus
possible to submit multiple
two-dimensional arrays, where each array can execute one or more
